SOLIDIFIED FIBER BUNDLES - A method for producing solidified fiber bundles includes applying a melt or solution to a carrier web forming a viscous coating, applying parallel filaments under tension to the carrier web, and pressing the filaments into the viscous coating, forming an impregnate. The coating is partially solidified until a plastically deformable state of the impregnate is obtained by vaporizing the solvent, thermal curing and/or cooling. The impregnate is rolled onto a winding core to form a roll while maintaining a winding tension of the filaments in the impregnate. The outer roll is fixed on the winding core by a sleeve and/or by adhesive tape. The impregnate is solidified by vaporizing the solvent, thermal curing and/or cooling. The solidified impregnate is divided up to form solidified fiber bundles. A pressure produced by the winding tension of the filaments in the impregnate is exerted on the roll.

PRODUCTION OF CARBON-FIBER REINFORCED COKE - A method produces carbon fiber-reinforced coke. Carbon fiber-reinforced plastic (CFRP) materials derived from components and semi-finished products are continuously fed through a top side of the drum of a delayed coker as a partial flow or as a main flow, and the CFRP materials sink through the gas phase into the still liquid phase. The carbon fibers are released through carbonization of the resin matrix and incorporated therein during the coking process. The decomposition products of the resin matrix are supplied to a material recovery process.
